Wireless Power Antenna Measurement for Foreign Object Detection

The patent segments the measurement process into multiple individual measurements taken at different time points during power cessation periods. By performing multiple separate voltage measurements and evaluating their consistency, the system can distinguish between voltage changes caused by communication signals versus those caused by foreign substances, thereby maintaining detection accuracy while allowing continuous communication functionality.

The patent implements a feedback mechanism where multiple voltage measurements are taken and their consistency is evaluated. The system uses the measurement results to determine whether communication signals are present and interfering with the detection process. Based on this feedback, the system can identify when measurements are compromised by communication interference and adjust its foreign substance detection accordingly, thereby enabling accurate detection while accounting for communication signal interference.

The patent performs preliminary actions by taking multiple voltage measurements during power cessation periods before making a final foreign substance determination. By pre-collecting multiple measurement data points and evaluating their consistency, the system builds a more reliable basis for detection. This preliminary measurement phase reduces the need for complex real-time analysis and simplifies the overall determination process while enhancing detection reliability.
